Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a curative treatment for numerous hematological malignancies. However, acute graft-versus-host disease (aGVHD) is still the major complication causing mortality. MicroRNAs (miRNAs) play a significant role in inflammation and have potential as prognostic and diagnostic biomarkers. This study investigated the role of two immune-spe...
Iron overload prior to allogeneic hematopoietic stem cell transplantation (allo-HSCT) due to blood transfusions is associated with increased non-relapse mortality (NRM) and with low overall survival. After allo-HSCT, high iron content in liver biopsies and elevated ferritin concentrations in blood, used as a surrogate parameter for iron overload, are also related to NRM. The cellular and molecu...
چکید ه سابقه و هدف gvhd بیماری است که در 40-20 درصد از گیرندگان پیوند هماهنگ از نظر hla دیده می شود. شماری از پژوهش ها نشان داده اند که چند شکلی در ژن های سایتوکاین، بر مشکلات پس از پیوند تاثیر می گذارد. یکی از اعضای این خانواده( il-1rn ) آنتاگونیست گیرنده (il-1ra)il-1 را کد می کند که یک مولکول با خاصیت ضد التهابی است و با il-1 a و il-1 b در اتصال به گیرنده رقابت می کند. میزان شرکت il-1 در ...
One of the major challenges of allogeneic stem cell transplantation (allo-SCT) is to reduce the risk of graft-versus-host disease (GVHD) while boosting the graft-versus-leukemia (GVL) effect. The reconstitution of natural killer (NK) cells following allo-SCT is of notable interest due to their known capability to induce GVL without GVHD. Here, in this study, we investigate the association betwe...
Allogeneic hematopoietic stem cell transplantation (HSCT) represents a potentially curative therapy for various malignant and non-malignant hematologic diseases. However, a frequent and severe complication of this therapeutic approach is acute graft-versus-host disease (aGVHD) characterized by immune-mediated inflammation and tissue destruction. In this context, donor-derived CD4 Thelper (Th) c...
Acute graft versus host disease (aGVHD) is a key complication of haematopoietic stem-cell transplantation. The main first-line therapy is steroids, however less than half of patients respond to this treatment, and some patients relapse following an initial response. Extracorporeal photopheresis (ECP) is a therapy that has shown promising efficacy in several immune-mediated disorders, including ...
The efficacy and the safety of the administration of multipotent mesenchymal stromal cells (MMSCs) for acute graft-versus-host disease (aGVHD) prophylaxis following allogeneic hematopoietic cell transplantation (HSCT) were studied. This prospective clinical trial was based on the random patient allocation to the following two groups receiving (1) standard GVHD prophylaxis and (2) standard GVHD ...
Using B-cell rearrangement excision circle measurements, we analyzed B-cell reconstitution in a cohort of 243 patients who underwent allogeneic stem cell transplantation. Acute and chronic graft-versus-host disease (aGVHD and cGVHD, respectively) transiently increased B-cell replication but decreased overall B-cell neogenesis with a clear difference in terms of kinetics. Moreover, the impact of...
Acute graft-versus-host disease (aGVHD) is still a major obstacle in clinical allogeneic bone marrow (BM) transplantation. CD4(+)CD25(+) regulatory T (T(reg)) cells have recently been shown to suppress proliferative responses of CD4(+)CD25(-) T cells to alloantigenic stimulation in vitro and are required for ex vivo tolerization of donor T cells, which results in their reduced potential to indu...
It has been shown that in vivo and in vitro treatment with G-CSF induces the generation of low-density granulocytes (LDGs), which copurify with PBMCs and inhibit IFN-gamma production by human T cells. These results prompted us to postulate an immunomodulatory role for LDGs in acute graft-versus-host disease (aGVHD). Here it is shown that in the mouse experimental model, in vivo and in vitro G-C...
